title: Diagnosis of digestive deaths.
abstract: Diagnosis of deaths due to digestive disorders can be a difficult task. It is helpful if the carcass can be viewed for condition, position, and location before being moved from the pen in which it was found. A complete necropsy is absolutely necessary even though postmortem decomposition may be advanced. All thoracic and abdominal organs must be examined for gross lesions. If one believes that the central nervous system was involved, the brain should be removed and examined. Checking the ruminal pH is important. If indicated, samples should be obtained and submitted to a diagnostic laboratory. Salient lesions include congestion of the anterior portion of the carcass, especially the cervical muscles and tissues adjacent to the esophagus and trachea, paleness of the posterior portion of the carcass, edema between the muscle groups of the hindquarters, scrotal, or mammary area, and a lack of other gross lesions. Many cases have congestion and(or) edema in the submucosa of the dorsal portion of the trachea extending from the thoracic inlet cranially. One must list the cause of death as unknown or undetermined when it is not apparent.
